Do not generate KeyPress events for non-printable characters
Eliminated memory allocations in Keyboard events
Cache size of char

BlittableValueType<char> caches the size of the type parameter. This
way, we avoid calling Marshal.SizeOf repeatedly for every keyboard
event.
Added nuget build target

This will create a nupkg file for OpenTK and copy it to the base
directory. Version information is currently hardcoded to 1.1 (this
should be fixed.)
Added nuget build target to OpenTK.sln
Added nuget lib directory to gitignore
Added release notes for OpenTK
Copy build artifact to root directory regardless of artifact name
Generate both build timestamp and version information
Do not commit build timestamp to repository
Improved nuget version information
Generate xml documentation for OpenTK.GLControl
Generate nuget package for OpenTK.GLControl
Updated description
